Abstract (en)
[origin: GB2597077A] In a processing unit having a register file a data cleansing mode is provided in which the write enable signals of all registers in the register files are simultaneously asserted to cause cleansing data values to be simultaneously written to all registers. Each register has a write enable input and the write data input, the write data input being connected to a write data path. In a normal mode of operation, the write enable signal of a respective one of the registers is asserted to cause operational data values to be written to that register from the write data path. In the data cleansing mode, all write enable signals are simultaneously asserted such that cleansing data values on the write data path are simultaneously written to all registers.
